	I've heard of lots of problems with machines using cross-over 
cables.  Can you connect the machines through a switch, and ensure 
that they are hard-wired to 100Base-TX full duplex at both ends, as 
opposed to auto-negotiating?

	I've also heard of lots of problems with some machines when the 
cable is too short, at least in certain combinations.  Try 
successively longer lengths of cable, at least up to 20-30m.
